The Minnesota Vikings have addressed their need for depth at linebacker, claiming fourth-year pro Xavier Adibi off waivers from the Houston Texans, according to his agent.

Adibi, 26, played in 34 games (eight starts) over three seasons with the Texans, who drafted him in the fourth round (118th overall) of the 2008 NFL Draft. He started against the Vikings in Thursday's exhibition finale and finished the preseason with 14 tackles, two sacks and three quarterback hits.

At 6-foot-2, 242 pounds, Adibi was a backup inside linebacker in Houston's 3-4 scheme. He also played inside in a 3-4 defense at Virginia Tech, so he'll have a transition to the Vikings' 4-3.

Adibi's agent, Andy Ross, confirmed his client was expected to be on the field when the Vikings resume practice on Monday morning. The Vikings assume the final year of Adibi's rookie contract, which includes a 2011 base salary of $555,000 and a cap number a little higher than that.

It wasn't immediately clear who the Vikings cut to make room for Adibi, but odds seemed good it wasn't a linebacker. They kept only five on the initial 53-man roster on Saturday.
